Example program - TinyTim

[clasqm]

It turns out that you can access tinyurl.com with a single line of bash script. So of course I had to write a 150-line front-end for it.

Code:

#!yab
############# Prologue #############

##Fill in these fields with your own particulars.
##The variables will be used in the About Box

ProgramName$ = "TinyTim"
AuthorName$ = "Michel Clasquin-Johnson <clasqm@gmail.com>"
ProgramVersion$ = "V0.1"
ProgramBriefDescription$ = "TinyTim allows you to send a long URL to tinyurl.com and copy the resulting short URL to the clipboard."
ProgramLicense$ = "Public Domain"

//*****Global Variables****

## Technically, yab does not require you to declare global variables,
##It just is a really, really good idea to do it anyway.
// set DEBUG = 1 to print out all messages on the console
DEBUG = 0
//change this to DEBUG = 0 when you are ready to bind the program for distribution

LongURL$=""
ShortURL$="Shortened URL will appear here after conversion"

######Preliminary Commands#####

## Commands to run before the Main Loop come here.
## e.g. setting up a window with a menu.

OpenWindow()

//Main Message Loop
dim msg$(1)
while(not leavingLoop)
    nCommands = token(message$, msg$(), "|")
    for everyCommand = 1 to nCommands
        if(DEBUG and msg$(everyCommand)<>"") print msg$(everyCommand)
        switch(msg$(everyCommand))
            case "_QuitRequested":
            case "MainWindow:_QuitRequested":
                leavingLoop = true
                break
            case "aboutButton"
                Alert ProgramName$ + " " + ProgramVersion$ + "\n" + "by " + AuthorName$ +"\n\n" + ProgramBriefDescription$ + "\n\n" + ProgramLicense$, "OK", "none"

    //Close down the main window
    window close "MainWindow"
end sub

sub Copy2Clipboard()
    if ShortURL$ = "" return
    clipboard copy ShortURL$

    draw flush "ShortURLView"
    Draw text 0,20, ShortURL$, "ShortURLView"

    //this should only happen at program launch

    Textedit 71,11 to 389,49, "URLField", 0,"MainWindow"
    Button 70, 60 to 390, 90, "tinyurlButton", "Submit this URL to tinyurl.com", "MainWindow"
    
    View 70, 100 to 390, 130, "ShortURLView", "MainWindow"
    
    Button 70, 140 to 280, 170, "copyButton", "Copy to clipboard", "MainWindow"
    option set "copyButton", "enabled", 0 //don't need this until we have a short URL
    Button 290, 140 to 390, 170, "aboutButton", "About", "MainWindow"
    
    DisplayShortURL()
    
    ExamineClipboard()
end sub

sub UIOnOff(state)
    //state must be 1 or 0
    option set "tinyurlButton", "enabled", state
    option set "copyButton", "enabled", state
    option set "aboutButton", "enabled", state
end sub

It comes out looking like this:


If there's already a URL in your clipboard when you launch the program, it will be detected and pasted in for you.

I like it better with a textcontrol instead of textedit:

Code:

#!yab

##Fill in these fields with your own particulars.

ProgramName$ = "TinyTim"
AuthorName$ = "Michel Clasquin-Johnson "
ProgramVersion$ = "V0.1"

ProgramLicense$ = "Public Domain"

//*****Global Variables****

// set DEBUG = 1 to print out all messages on the console

//change this to DEBUG = 0 when you are ready to bind the program for distribution

Ends up looking like this:

That could go either way. I had in mind very long URLs that may need an extra line to be displayed in full.
